Solution Overview

Problem

The existing methods for forming a house connection require significant earthworks, multiple excavations, and backfilling, leading to high costs and complex scheduling, while also damaging building insulation and reducing usable living space due to the need for interior connection rooms.

Innovation Solution

An external service connection room is designed as a self-supporting, prefabricated structure located outside the building, equipped with a multi-branch entry for various supply lines and devices, allowing for flexible and independent connection to the building's infrastructure without penetrating the building shell.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If house connection is formed by penetrating building shell with core drilling, then connection to supply lines is achieved, but building insulation is damaged and living space is reduced

Engineering Contradiction:
Improveconnection reliabilityVSAvoidinsulation damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the house connection function from the building interior by placing an external connection box outside the building shell. This eliminates the need for core drilling through the building, thereby preserving the building's insulation and structural integrity while maintaining reliable connection to supply lines

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The external connection box serves as an intermediary element between the building and the supply lines. It provides a dedicated connection point outside the building that mediates the connection process, avoiding direct penetration of the building shell and its insulation layer

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple excavations are performed for connecting supply and disposal lines, then connection flexibility is improved, but earthwork effort and costs increase

Engineering Contradiction:
Improveconnection flexibilityVSAvoidearthwork complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges multiple connection functions (supply lines, disposal lines, and future expansion connections) into a single external connection box. This consolidation reduces the need for multiple separate excavations while maintaining the flexibility to connect different types of lines through the unified structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The external connection box is installed in advance during building construction, preparing all necessary connection points and access openings before actual utility connections are made. This preliminary action eliminates the need for subsequent excavations and backfilling when connecting supply and disposal lines

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If house connection room is placed inside the building, then connection access is improved, but usable living space is reduced

Engineering Contradiction:
Improveconnection accessibilityVSAvoidliving space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The invention extracts the entire house connection room from the building interior and relocates it to an external position. The connection box is placed outside the building shell with access openings facing outward, providing full connection accessibility while preserving 100% of the building's interior living space

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention moves the connection function from the interior three-dimensional space of the building to an external location, utilizing the space outside the building envelope. This dimensional relocation eliminates the trade-off between connection accessibility and living space utilization

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
